【摘要】 路面结构的早期破坏与公路货运的超载超限有直接关系.由于汽车货运向大型重载方向发展,货车的 总质量有增加的趋势,使得公路运输超载超限等问题日趋严重.为了缓解这一矛盾,以广西平(果)-百(色)二 级公路的路面破坏为例,结合大量实测交通量综合分析了交通量和车辆超载对水泥混凝土路面破坏的影响,并 计算了超载车辆对路面荷载应力和厚度的影响.更多还原

【Abstract】 Much of the early destructions of pavement structure have directly relation with the overload vehicles. The weight of truck is with the development tendency of heavy truck load. This make the overload condition rather more serious. This paper analyzes the destruction of over loaded vehicles for cement concrete pavement on Highway Pingguo-Baise, Guangxi. On the basic of great amounts of data of traffic volume and overload, the influences of traffic volume and truck overload were analyzed, and results of load stress and thickness of pavement are calculated for over loaded vehicles.更多还原
